Plug-ins

or, pepperoni for your cheese pizza

In the early days of the World Wide Web, the first versions of HTML couldn’t deliver fancy content like videos. Text, images, and links were pretty much the limit.

Plug-ins were invented to work around the limitations of early HTML and deliver more

interactive content. A plug-in is an additional piece of software that specializes in processing particular types of content. For example, users may download and install a plug-in like Adobe Flash Player to view a web page which contains a video or an interactive game.
